How do you improve on near-perfection? It's quite possible that the answer to that question is the Reaction SL. Light, agile and equipped to take on any trail and any competitor, it's the bike that will transform any ride into a motion-blurred celebration of speed. With our newly revamped 2018 Reaction frame and a component selection that reads like a wish-list, your legs will be screaming for you to stop long before you want to give up. Fox's plus 32 Rhythm fork, Shimano's peerless XT transmission and brakes and fast-rolling, CUBE-built wheels complete a package that's ready to rock. The question is, are you?

Our engineers took their time and ticked all the boxes with the Reaction SL. Mechanically formed, double butted 6061 aluminium tubes for low weight and superb acceleration and control? Check. Fully integrated, sealed bearing headset for long life, low stack height and accurate steering? Present and correct. Internal cable routing for all cables including a future upgrade to a Stealth dropper post? Of course. Thru axle rear end for even greater torsional rigidity? Well, it'd be rude not to on a frame like this. Put it all together with our Agile Ride Gometry for the ride-by-wire nimbleness you'd expect from a CUBE race bike, and it's a winning formula whether you're racing, or just riding for fun.
